-----------------------------------
[~jamestaylor]: Please find attached the Initial patch.
Problem 1:
In eclipse, i ran through the code(using SecureClusterConnectTest class) to
connect Phoenix to HBase and it successfully connects to the cluster. However,
after connecting i get ClassNotFoundException error:
Exception in thread "main" java.lang.RuntimeException:

Phoenix is referring to hbase-0.94.12 jar. To my surprise,
org.apache.hadoop.hbase.ipc.SecureRpcEngine class is not present in that
version. I am running my cluster on cdh4.5.0. and cdh4.5.0 hbase jar has that
class.
Problem 2:
After compiling phoenix with patch, i tried to run phoenix using sqlline.sh
script on non secure cluster by using command:
sqlline.sh jdbc:phoenix:<zk>
I get this error:
com.salesforce.phoenix.jdbc.PhoenixDriver
java.lang.NullPointerException
sqlline version 1.1.2
I have enabled debug logs but still i dont get any logs when i invoke phoenix
on console.
Could you please review the code and tell me how to resolve the above two
problems. Thanks.
